My pleasure. 3D printing is still very much a tinkerer's art as much as it has any science, and you have to be willing to get out in front of it and understand that problems can have many sources.

So far I've been extremely lucky with the low cost printer that I chose to be my primary, but I am trying to stay aware of all of the problems that can come up in the course of operations. That is a lot of continuous research and staying on top of things.
